I am not asking if it's advisable. I only want to know how realistic such an endeavor would be.

If you knew about setting up sites, themes, plugins, analytics, adwords, integrating with social media, etc. But knew very little html/css, php, mysql, javascript, or flash. Could you still run a small business?

Let's further suppose you had access to programmer's for the times you needed them so you could sub-contract.

Could such a business be feasible?
